BACKGROUND

[0001] 1. Field of Invention

[0002] The present invention relates to hearing aid with various changesof shapes, more particularly to free hearing aid providing multi-shapeand multi-function. The components of hearing aid—ear tip, shell,faceplate cover, faceplate, and battery room cover etc.—that arestandardized suitably to various sizes of many people is produced on alarge scale, and a coupling production that can combine and separatecomponents of hearing aid easily changes the form of the hearing aidvariously. Also, because only the replacement of battery room covertransforms the volume of a battery room, battery capacity of varioussizes can be used.

[0003] 2. Description of Prior Art

[0004] Hearing handicapped people in order to hear more surely andcomfortably uses hearing aid commonly. These and other features, andoperations of the conventional hearing aid, accompanying drawings, is asfollows.

[0005]FIGS. 4, 5, 6 are a fragmentary perspective, a coherentperspective and a plane of the prior art. The structure of conventionalhearing aid (900), as described in FIGS. 4, 5, 6, comprises shell (700),which is copied from the pattern of ear based on an auricle and externalear of the user and is made by handiwork; faceplate (800) combined withshell (700) by adhesives, which is connected and equipped on amicrophone (460), an amplifier (420), a receiver (360), a battery room(870), and a sound controller (440); a microphone (460) equipped onfaceplate (800), converting sound signal into electronic signal andconnecting amplifier (420) by connecting lines; an amplifier (420)equipped on faceplate (800) as a shape of a chip, amplifying electronicsignal enough that comes from microphone (460); a receiver(360), linkingby the connecting lines of the amplifier equipped on faceplate (800) andconverting amplified electronic signal into sound signal; a sound guidetube (310), transmitting sound signal converted from receiver(360) andoffering an output to the upper end outlet of the shell(700); a fixedcover of the receiver(320), fixing receiver(360) to the sound guide tube(310); a sound controller (440), linking by the amplifier (420) equippedon faceplate (800) and controlling volume of a sound by user of thehearing aid; a battery room (870) equipped on faceplate (800),possessing a battery supplied the source of electronic power to amicrophone (460), an amplifier (420), a receiver (360); a door ofbattery room (850) fixed on the lower end of faceplate (800).

[0006] But, a type of the shell (700), which is copied from the patternof ear based on an auricle and external ear of the user and made byhand, varies with the pattern of the ear of user. For that reason,because the standardization of the shell that is fitted to the patternof ear by various sizes of many people is impossible, production on alarge scale of hearing aid is very difficult.

[0007] Besides, the cohesion of the shell (700) and the faceplate (800)is adhered to outer section of the lower end of the shell (700) and topsurface of the faceplate (800).

[0008] Accordingly, when mending and replacing work is occurred by thedefect of hearing aid component equipped on faceplate (800), the shell(700) and faceplate (800) equipped on hearing aid component mustseparate. As a adhesive portion of outer section of the lower end of theshell (700) and top surface of the face plate (800) must separatecompulsorily, damage of component equipped on surface of the shell (700)and the face plate (800) and a cut of separation worker by use of tool(knife, etc.) for compulsory separation occur on this process.

[0009] And, but a volume of the hearing aid differ according to sizes ofan auricle and external ear of the user, this difference is so smallthat a small size and capacity of battery is more adjustable than a hugesize and capacity.

[0010] But, in order to use hearing aid for many hours, a huge capacityof battery is needed. Though the conventional hearing aid (900) uses asmall capacity of battery that must increase a volume of battery (870)in order to use a huge capacity of battery, a conventional volume ofbattery (870) is restricted by a regular capacity of battery size.Therefore, without alteration of an external structure of hearing aid,increase of a volume of battery (870) is impossible.

[0011] And, most of user's ear secretes earwax. Earwax make clean theinside structure of ear, on the other side, earwax flows in a receiverthrough sound guide tube of hearing aid. If earwax flows in a receiver,a fit operation of the receiver is blocked up and a disorder of thereceiver is caused.

SUMMARY OF THE INVENTION

[0012] In order to overcome the conventional problems, an object of thepresent invention is to produce ear tip, shell, faceplate cover,faceplate, and battery room cover etc. on a large scale according to apattern of ear that is standardized fitly to various sizes of manypeople, and cut down manufacturing cost of hearing aid by production ona large scale.

[0013] Another object of this invention is to provide improved mendingand replacing process without damage of hearing aid components by easycombination and separation of hearing aid components when disorder ofcomponents is occurred.

[0014] A further object of this invention is to embody an epoch-makingprocess of hearing aid that produces each component independently, whichis altered function of some component without structure alteration ofanother components and is to provide a diversified function of hearingaid by cohesion structure.

[0015] A still further object of this invention is to provide a hugesize and capacity of battery that uses for many hours. Without thestructure alteration of the hearing aid, only transformation of batteryroom cover that can be transformed a volume of the battery room, whichis inserted a battery, is able to use a small size and capacity of abattery for many hours.

[0016] An additional object of this invention is to prevent disorder ofhearing aid from earwax that interrupts a fit operation and output ofpower of the receiver. Earwax flowing in the receiver through soundguide tube is cut off by a minute netting cover of outer portion of thereceiver.

[0039] The invention will now be described with reference to theaccompanying drawings wherein.

[0040]FIGS. 1, 2, 3 are a fragmentary perspective, a coherentperspective and a plane of the free hearing aid providing multi-shapeand multi-function according to the present invention.

[0041] The ear tip (100), as described in FIGS. 1, 2, 3, is standardizedfitly to various sizes of many hearing aid users.

[0042] Especially, the ear tip (100) and the shell (200) are made bystructure of combination and separation. Because the shell isstandardized fitly to various sizes by a cohesion groove (220) and acohesion sill (120), many hearing aid users are able to use hearing aidfitly.

[0043] Besides, as the quality of the material of the ear tip usesilicon that provided smooth and comfortable wearing, a sanitary problemis not occurred by contacting of the surface of the external ear and atransformation of the silicon by constriction and swelling is possibleaccording to size of the inside diameter of external ear.

[0044] Because the shell (200) is made by the ear tip (100), a cohesiongroove (220) and a cohesion sill (120) with the structure of thecombination and separation that are standardized fitly to various sizesin the upper end of the shell (200) and faceplate cover (300), acohesion groove (240) and a cohesion sill (310) in the lower end of theshell (200), a pattern of the ear standardized suitably to various sizesof many hearing aid users are able to use hearing aid fitly.

[0045] Inside of the shell (200) is equipped on sound guide tube (260)that installed 4 locking sills respectably to inner portion in thedirection of an angle of 90 degrees. Therefore, when a sound signal ismoving to the outlet of the outer cover, a pressure of sound is improvedby changing of inside density because of 4 locking sills.

[0046] As the quality of the material of the shell (200) use siliconthat provided smooth and comfortable wearing, a sanitary problem is notoccurred by contacting of the surface of the external ear and atransformation of the silicon by constriction and swelling is possibleaccording to size of the inside diameter of external ear.

[0074] The ear tip (100) and the shell (200) are standardized fitly tovarious sizes (15-a, 15-b, 15-c) of many hearing aid users.

[0075] Accordingly, the ear tip (100) reduced and altered uniformly by asize of the inside diameter of external ear is made in various andstandardized sizes. Because the shell (200) use a reduced and alteredsilicon uniformly that can be transformed by constriction and swellingaccording to a structure of external form of an auricle and a size ofthe inside diameter of external ear, the shell (200) is made in variousand standardized sizes.

Therefore, as a pressure of soundis improved by changing of inside density of sound guide tube (260), amaintaining of a direction of a sound wave prevents a transformation ofa sound wave.

[0078]FIG. 17 is a perspective of a net filter in order to protect thereceiver according to the present invention.

[0079] The net filter (340) installed minutely to the outer portion ofthe receiver (360) prevents earwax that is flowing in receiver throughthe sound guide tube (260) and protects the receiver (360).

[0080]FIG. 18 is a making process of the shell of the conventionalhearing aid.

[0081] The making process of the shell is as follows:

[0082] The spout process (18-a) is to spout and insert to the surface ofthe ear (710) of hearing aid user through injector (730) inserted thesilicon.

[0083] The separation process (18-b) separates ear mold (730) that iscopied from a shape of ear, and that become hard in the condition of gelon the surface of the ear (710).

[0084] The cutting process (18-c) cuts the separated ear mold (730)fitly to a shape of ear.

[0085] The mixing process (18-d) lays the cut ear mold (740) on thecenter portion working board, and puts a beaker (750) of a column shapeof both sides open on the ear mold, and pours AGAR on sol conditions ofchemistry solution into the inner portion of a column.

[0086] The mold creation process (18-e) is created mold in the upper endportion of AGAR. After the ear mold (740) and the column poured AGAR ofan invariable ratio let cool completely in water, turning out theworking board, and removing the working board and the column, the moldand AGAR that become hard on the mold leave into the column shape beingturned upside down in an angle of 180 degrees. At this time, the earmold (740) is placed on the upper end portion of the column. As the earmold (740) placed on the upper end portion separates from AGAR thatbecome hard, a separated mold shape is created in the upper end portionof AGAR.

[0087] The process of pouring in (18-f) is to pour a resin of mixingsolution into the mold of AGAR.

[0088] The final process (18-g) is to put final touches and cutting on ahardened resin that is separated from AGAR after hardening of a limitedtime.

[0089] Consequently, the present invention has some advantages asfollows.

[0090] A pattern of ear of hearing aid user is different according toeach and every person. If the making process of the shell by handiworkis improved, production on a large scale of the shell can be possible bystandardizing with various sizes of a pattern of ear. Therefore, as aprocess of handiwork decreases in making process, manufacturing cost ofhearing aid cut down by shortening of manufacturing term.

[0091] Besides, this invention is to provide improved mending andreplacing process without damage of hearing aid components by makingeasily combination and separation of hearing aid components whendisorder of components is occurred. Only alteration of some componentcan be altered a function of hearing aid variously.

[0092] Moreover, only transformation of battery room cover, because asmall size and capacity of a battery transforms into a huge size andcapacity of a battery, an equal battery can use for many hours withoutreplacement of a battery. Also, as a price of a battery of huge capacityis equal with small battery, use of a battery of huge capacity can cutdown a cost sharply.

[0093] Besides, an effect of this invention is to prevent disorder ofhearing aid from earwax that interrupts a fit operation and an output ofpower of the receiver. Earwax flowing in the receiver through soundguide tube is cut off by a minute netting cover of outer portion of thereceiver. That is, the expected life span of hearing aid make longer.

[0094] Moreover, as the locking sills (280) formed in inside of thesound guide tube (260) improves a pressure of sound by changing ofinside density of the sound guide tube (260), a maintaining of adirection of a sound wave prevents a transformation of a sound wave.
